Announcement (2017-05-07): www.ruby-forum.com is now read-only since I
unfortunately do not have the time to support and maintain the forum any
more. Please see rubyonrails.org/community and ruby-lang.org/en/community
for other Rails- und Ruby-related community platforms.

A few hours ago, Henon announced the new version of foxGUIb, for
creating user-interfaces.
He also mentioned a surprise, and I know you have been holding your
breath :)
I've written a user-guide for it, aimed at the beginner.
Why don't you check out foxGUIb together with its guide?
The link to the software is:
http://fox-tool.rubyforge.org/
and the above link also points you to the guide. The direct link to the
guide is:

Enjoy!
Best wishes
Mike Parr
